and think you’ve seen it all…
What you really need is a holiday in science…

It’s beginning to sound a lot like TWISmas
Intro to the show
A pair of NASA probes, and a rover that roves
Is the wish of Barney and Jen…
A robot that talks and will go for a walk
Is the hope of Janice and Ben…

Such a beautiful sight
Happy tonight
Talking in a science wonderland

As we hoop de do and dickory dock
into the holiday season
With science stories comin’ around

We want to wish you a merry TWISmas
we wish you a merry TWISmas
and a happy new year…

before we are off

Dashing through the show.
In a science podcast sleigh.
On the air we go – This Week in Science on the way
Coming up next…

Let’s start with some quick science news

Krypton Origins
This origin story for volatile elements on Earth concludes that much of the carbon, nitrogen, & water arrived before the moon-forming impact, and that there are multiple sources for these elements in the mantle & atmosphere.

Heart of the sun
Parker Solar Probe has dipped into the sun’s corona and discovered a lot of fascinating things.

Defusing A Bomb
Thanks to sterilization, contraception, & education, India now has a fertility rate below the replication rate of 2.1 children per household.

Dog/ fish/ worm parasite
Pet Dragons?

New Organs
How do they evolve?

14 new mammals described
New shrews to fill out the mammalian family tree! And, perhaps a new version of a Christmas carol?

Want a COVID Update?

COVID Update
Omicron continues to spread rapidly around the globe spurring heightened alerts by public health agencies & local governments. At least one American university, Cornell, has shuttered in-person finals & graduation as a result of a dramatic increase in COVID-19 cases & evidence of omicron in the hopes that it will prevent a larger outbreak in the community at large. Scientists are warning that although omicron might not result in serious disease as often (especially with high rates of vaccination & previous infection in many places) the transmissibility is enough that the sheer number of cases will overload hospitals IF prevention isn’t taken seriously.

TWISmas Safety List – Check it twice!
– Get your booster if you are vaccinated.
– Take ventilation & masks seriously.
– HEPA filtration works!
– N95 for the win!
– Be transparent – talk openly with friends & family about risks
– Rapid testing is your friend.
– So is PCR.
– Think about ways to reduce your potential for infection – can you isolate in the days before festing?

If you have concerns, talk to a doctor, check the CDC website,
& do your best to keep your community protected.
We re in this together.

Retracted Study
Study finding no effect of lockdowns on COVID-19 deaths found to have faulty methods unable to actually find such effects if they did indeed exist.
